I have a question about this test question:
Chemotherapy given at the same time as radiation therapy can help patients with a certain type of lung cancer live nearly 50 percent longer than they ........ otherwise if the same treatment ...... differently.
- may have / will be given
- might have / was given
- could have had / would be given
- would have had / would have been given
The answer is 2.
Why did it use "might have"? Why not for example "might"?
... help them live longer than they might have
What?! They might have lived? In this way it won't be a 2nd conditional. Using "was given" is correct I think, because he is talking about an imagination and a thought in the present tense and it is similar to the concept of conditional sentences type 2.
